Convenient access to carbohydrate - BODIPY hybrids by two complementary methods involving one-pot assembly of >clickable> BODIPY dyes

摘要

Two complementary one-pot, three component synthetic strategies based on copper(I)-catalyzed azide - alkyne cycloadditions (CuAAC) have been developed, which allow the efficient assembly of glycosyl-derived alkynes or azides with highly fluorescent boron-dipyrromethene (BODIPY) cores containing azido or alkyne moieties, respectively. The resulting carbohydrate - BODIPY derivatives display excellent photophysical and laser properties that relate to the spacer (amino group or aromatic ring) employed in each of the synthetic protocols.
